{SPECIFICATION forming part of Letters Patent No. 274,252, dated March 20, 1883.

' Application filed November 13, 1882. (No modelJ To all whom it may concern:

" zen of the United States bf America, residing at Yuba,iu the county of Richmond and State of Wisconsin, have invented certain new and useful Improvements in Oh urns and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to certain improvementsin that class of churns which are known to the trade as end-over-end revolving churns and it consists in providing a churn of the aforesaid class with, a central guide-rod, upon which is located a sliding dasher, as will be hereinafter more fully set forth and pointed out in the claim.

Inthe annexed drawings, Figure l is a perspective view of my improved churn. Fig. 2 is averticallongitudinal section taken through the line or w of Fig. 1. Fig. 3 is a transverse section taken through the line yy; and Fig. 4 isa plan view, showing the top of the churn and cover. 7

In the annexed drawings, A represents the supporting-frame, which consists of side bars, which are united at their upper part to form bearings, and at their lower part by suitable cross-bars, the upper end of said side bars being cut away or recessed for the reception of the side journals of the churn-body. This frame is ofa sufficient height to allow the churn to revolve within the frame above the crossbars which unite the lower part of the standard.

B represents the churn-body, which is preferably rectangular in shape, and is of a greater length than width, and it is provided on its opposite side with journals 0 G, which are attached to the central portion of the body, as shown. One of these side journals is provided with acrank-handle, a, or other suitable means,

whereby the body can be rotatedor turned end over end.

The lower end or bottom of the churn-body is provided on its exterior portion with a counter-weight, D, which is secured to the body of the churn by wood-screws. The

interior of this counter-weight is composed of' soft metal, so that it can be readily removed openings, on the under side'of the ring F, are

beveled or wedge-shaped inclines, which extend from one of these openings 6 0 near the lower portion of the adjacent opening, so as to form inclined sides,which will hold the top of the churn securely in place.

The cover F, which is removable, is provided on its upper surface with raised portions or handles f f, and on its periphery with outward-extending lugs M, which will fit into the openings of the frame F, and when turned toward the lower portion of the incline will hold the cover firmly in place, the incline acting as a series of wedges. The lower side of this cover F is provided with a central. socket or opening, h, for the reception of one of the ends of the guide-rod I, which guide-rod fits or is secured within a socket, g, in the bottom of the churn. Thus the guide-rod I,wh'en the cover is placed on the churn, is heltlsecurely in place.

Thedasher G may be of any suitable construction, and it is preferably made of metal or other. heavy material, so that it will slide upon the rodwhen the churn is rotated. This dasher is of a size so that it canbe removed from the churn through the opening E when thecover is removed.

If desirable, washers may be placed on the guide-rod at its end, so that the dasher will not strike directly upon the ends of the churn.

The operation of this invention may be described as follows: The churn is placed. in the supporting-frame and rests upon its side journals. The cover is then removed. The churn will then, owing to its weighted bottom, assome a vertical position. The dasher is then placed upon the guide-rod and the cream is poured within the churn, after which the cover is secured in place, as heretofore described.

When the churn-body is rotated or turned end over end, the cream is thrown from one end of the churn to the other, and the dasher, whichis constantly moving or sliding from one end of churn-body to the other, serves to further agitate the cream.

1 am aware that it is not new to provide a revolving or rotary churn with a central shaft to which is secured a rigid dasher or a rock-' ing churn with a sliding dasher, and I do not claim such as my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A revolving churn-body provided with a central guide-rod attached to the top and bot- 15 tom of the churn-body, and provided with a sliding dasher mounted on the guide-rod, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.
